HOLDER FOR LIGHT-DIFFUSING- BOWLS.

To all whom it may concern-x Be it known that I, HERBERT E. CAVE, a citizen of the United States, residing at indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Holders for Light-Diffusing Bowls, of which the fol. lowing is a specification.

This invention relates toimprovements in holders for light diffusing bowls and is primarily adapted. for use in connection with electric lights, the main feature of the invention being the provision of a holder which may be quickly and easily attached to the lamp socket and which will serve to hold a light diffusing bowl in proper alignment with the lamp at all times.

A further feature of the invention is in so constructing the socket attaching parts and the bowl supporting arms that the holder may be applied to use in connection with various makes of electric lamps or bulbs.

A further feature of the invention is in so constructing the socket engaging parts of the holder that the ordinary shade supporting trimmings or brackets may be readily engaged with the lamp socket, when such parts are used, certain elements of the shade supporting member clamping around parts of the holder, the holder being constructed to hold the shade support in fixed position.

A further feature of the invention is in so constructing the parts of the holder engaging the lamp socket that said parts will have more or less of an elongated bearing surface against the socket thereby resisting anyv twisting or tilting movement on the socketm-i-usioned by vibrations or other causes.

A 'lurther feature of the invention is in so constructing the bowl engaging parts of the holder that the tensions thereof will be sufiicient to hold said parts in engagement with and support the bowl under ordinary conditions.

Other objects and advantages will be hereinafter more fully set forth and pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application,

Figure 1 is a perspective View of the holder ready to be applied to use,

Figure 2 is a detail perspective view of a lamp socket showing the holder attached thereto and engaged by a clamping ring Figure 3 is a similar view showing the holder applied to the socket, together with the usual form of shade supporting member or bracket attached thereto, and

Figure at is a detail perspective view of a further modified structure.

Referring to-the drawings, 1 indicates the body of the holder which is preferably in the. form oi. a ring or circular, and is preferably formed in one piece, althoi'lgh it will be understood that the ring may be made in sections, if so desired, and secured together in any suitable manner. The diameter of the body 1 is such that it will readily pass over the end of the usual form of lamp socket 2, and the upper edge of the body 1 is proyided with. a plurality of integral tongues 3. These tongues are preferably uniformly spaced apart and are given an inward, substantially right-angled bend 4: at approximately the longitudinal center of the tongues thereby setting inwardly the upper portions or" the tongues, and providing more or less elongated bearing surfaces 5 for en gagement with the wall of the socket 2, and as practically all such sockets are provided with heads 6 adjacent their lower ends the shoulders formed by the inwardly bent portions 1- will rest on such bead when the lamp socket is suspended vertically.

In view of the extended bearing surfaces 5 on the free ends of the tongues 3, the body portion 1 will be held in perfect alignment with the lamp socket and the bulb connected therewith, and will not become tilted or moved out of alignment due to vibrations, as is common of other forms of holders.

Preferably integral with and depending from the lower edge of the body 1 are a pluality of legs 7, said legs having bends 8 therein which adapt them for fitting over lamps or bulbs of varying sizes and contours, the free ends of the legs having curved or rolled terminals 9 which engage the upper portion of a bowl 10 and suspend the same from the holder, the spring tension of the legs being such as to securely hold them in engagement with the bowl. If desired the legs may be provided with ribs 11 for strengthening or reinforcing them.

The holder is preferably formed from a single piece of metal, dies, or other tools being employed for forming and shaping the same, consequently producing a unitary, concrete structure. although it will be clearly understood that the holder may be built up of sections, and. such sections secured together in any preferred manner.

Under ordinary circumstances the tongues 3 will serve to retain the holder in suspended relation with the socket 2, but if preferred a collar 12 may be clamped around the upper ends of the tongues, as shown in Figure 2 of the drawing, or in cases where the usual form of shade supporting bracket 13 is employed the usual form of collar 14 associated therewith may be clamped around the free ends of the tongues, as shown in Figure 3 of the drawings. In some instances the holder may be constructed, as shown in Figure 4: of the drawings, in which the parts of the holder are stamped from a flat piece of metal and then shaped, the meeting edges of the body portion 1 being overlapped and spot-welded, as shown at 2 or said meeting edges may be secured to gether in any other suitable manner.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

A holder for light diffusing bowls, comprising a cylindrical body portion, a plurality of tongues integral with one edge of said body portion and spaced therearound, said tongues being bent inwardly between their ends for engaging the head of a lamp socket, and a plurality of resilient legs in tegral with the opposite edge of said body and bent outwardly and downwardly where by electric bulbs of Varying contour and size may be entered between said legs, said legs having longitudinal ribs formed thereon, and having their free ends curved or rolled for engagement beneath the upper inturned edge of a light difl'using bowl, substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Indial'iapolis, Indiana, this 30th day of November, A. D. nineteen hundred and twenty.
